I need in figuring out what I did wrong as the coefficient of friction seems to be to high of value

Givens O 0- = 60 Fretg = ooh vit +1 at ? Fneto = MA t = 1.465 FN = mgay FF - FAX= ra d = 0. 343 m FN = 0. 05 ( 1. 81 ) cos 75 FF = ma + mg sin 7s M= 0.05ka FN = 0. 127 N a= 2 (6.343) 1.462 FF = D. OS (0. 3218) + (0. 05) ( 9.81) sin 7S a= 03218 m /s FF = 0. 01609 +0.474 FF = MFN FN FF = 0. 490IN FF FN FF 6. 4201 0. 126 MK = 3.88 0. 05kg .Fg cos 75"
